≈ $50.5M–$95.0M after Steam's cut

All 8 of the similar games are hits.

No genre covers most of these similar games. The closest is First-Person (3 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: Wallpaper Engine at ≈ 31.0M–50.3M copies, ≈ $42.5M–$114.3M after Steam's cut. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share First-Person (3 of 8) and Anime (2 of 8).
The winners: Winners here lead with Mature + Utilities, priced around $5. The breakout hits carry Mature + Utilities + Software; a typical game here doesn't.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2019. That says more about which games were found than about the market.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 36 for the most recent game here to about 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
